..Recently, alanyl-L-glutamine has been used to replace glutamine in media for the culture of human preimplantation embryos. The results in this paper suggest that glycyl-L-glutamine may be a better choice of dipeptide...

Discrepancies between the effects of glutamine in cultures of preimplantation mouse embryos

..The results show that trehalose has a significant beneficial effect in preserving the developmental potential of mouse sperm following partial desiccation and storage at temperatures above freezing...

One-step versus two-step culture of mouse preimplantation embryos: is there a difference?

..05). The results demonstrate the feasibility of using a convective drying protocol for the successful desiccation of mouse sperm and identifies some of the important parameters required for optimization of the procedure...

Evidence that glucose is not always an inhibitor of mouse preimplantation development in vitro

..The slight inhibitory effects of KH(2)PO(4) appeared to be due to the inhibition of the development of a few sensitive embryos. No significant effects of glucose and KH(2)PO(4) were observed on the total cell counts...

Cyclin D2 is an FSH-responsive gene involved in gonadal cell proliferation and oncogenesis

..The hypoplasia seen in cyclin D2(-/-) ovaries and testes prompted us to examine human cancers deriving from corresponding tissues. We find that some human ovarian and testicular tumours contain high levels of cyclin D2 messenger RNA...

Coordinate action of Wt1 and a modifier gene supports embryonic survival in the oviduct

..These studies implicate Dicer1/miRNA mediated posttranscriptional gene regulation in reproductive somatic tissues as critical for the normal development and function of these tissues and for female fertility...
